WHEEL.

Application filed November 1, 1920, Serial No. 421,081. Renewed May 18, 1822. Serial No. 562,089.

To vall whom it may concern;

Be .it known that I, Gnonon A. Moon, a citizen of the United States, residing at Chicago, in the county of Cook. and State of Illinois, have invented a certain new and useful Improvement in -Wheels, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a ,part of this specification.

My invention relates to wheels and has to do more particularly with disk wheels for automobiles and the like, being directed more to the provision of a disk wheel havin certain features of improvement where y a. strong but resilient wheel is the result.

One of the features is the provision of a wheel disk which may be readily secured to the'standard type of wooden spoke hub having a flanged back and central tubular-portion,-the disk being centrally cupped so as to receive a cap therein whereby the parts may be readily secured together and a distribution had of the driving strain.

Another feature is the provision of a poculiarly shaped disk whereby although com- Daratively thin sheet metal is used, the wheel is resilient though stron enough to take the ordinary shock without injury.

Other features will be more articularly referred to in the ensuing speci cation and claims.

For a better understanding of my inventi n. reference is to be had to the accompanying drawing, in which- Fig. 1 is a transverse cross section through the wheel;

Fig. 2 is a face view of the cap for clamping the disk to the hub; V

Fig. 3 is a modified form showing a demountable rim, Fig. 1 showing the clincher 4 1s a modified form of disk clamping a central opening large enough to readily slip over the tubular portion 5 of the hub.

The wheel disk is also cupped in the middle by forming an outwardly extending port1on 8. By cupping the disk in this way, the clamping cap B will set into the cup ed portion so as to engage the edge thereo at the peripheral edge 9 of the cap. The cap B preferably fits snugly over the tubular portion 5 and a suitable number of bolts 10 passed through the parts to securely hold them together.- By this construction, the

disk is held firmly against the flange of the hub and the driving strain distributed and not all placed upon the frictional contact between the fiange 6 and central flat portion of the disk. That is, the clamping cap B takes the greater part ofthe strain by fitting snugly over the hub 5 and into the disk cup.. This cap B is preferably made of cast aluminum so that it ma be polished and partake of an attractive finish. A plurality of ribs 14 are provided so as to strengthen it;

Now in order to give resiliency to the wheel from road shock, I provide an annular recess or cup 11 and then a slightly curved disk portion 12 between the annular recess 11 and the telly 13. By providing the annular recess 11 and slightly curving the disk portionlQ, the wheel is a great deal stronger than if these portions were straight and at the same time provides a structure having some resiliency. By curving the portion-12 of the disk, the wheel is strengthened greatly against side shock, also providing a resiliency which-causes the disk to spring back to normal following any undue side strain.

In Fig. 1, I have shown the ordinary type of clincher rim 15 which is referably welded tothe telly 13 of the w eel disk which 'is referably' made of cold rolled steel.

11 order to enclose the end of the huh, I provide a hub cap 16 which is of a suitab e shape to enclose the exposed end of the hub and abut against the cap B.

It will be apparent that although I have referred to the wheel as being applied to the ordinary Ford hub, it ma be used in connection with the other stan ard types of hub, being used to great advantage for replacing wooden spoked wheels, by simply removing the old wooden spokes and fell and replacing them with my improved dis wheel.

Also, the parts are secured to ether in a simple way so that they may e readily assembledand taken apart for replacement with spare disks where the rim is 'of the clincher t and is permanently secured to the telly of the disk. y

I also contemplate using my improved disk in connection with demountable rims and have shown the well known Baker type in Fig. 3. The rim 17 is of the well known split type and held in place over the felly 13 by means of theusual clamp 18 and the bolt andnut 19. lVhen using the demountable rim, the rim itself may be changed without carrying an entire spare disk wheel, where desired.

- In Fig. 4 I have shown the cap B as hav-' ing a hub cap 16 formed integral therewith, being preferably cast as a portion of the capB and all polished so as to partake of an attractive finish.

' Although I have shown my invention in several preferred forms, I contemplate ap plying it'in other ways and appreciate that changes and modifications will readily occur to those skilled in the art and therefore do-not'desire to be limited to the exact structures shown and described but aim to coverall that which comes within the spirit and scope'of the appended claims.

cla1m'a-- v 1. A disk wheel comprising a flanged hub,

a single centrally cupped disk removably fitted over the hub .and'having the outside seat of the on resting against the hub flange, a capa so fitted over the hub and having a peripheral edge resting against the disk cup, and means for securing the hub, disk and-ca together.

2. A disk-whee comprisin a flanged hub, a single ce'ntrally-cup ed isk removably fitted-over the hub an havin the outside seat of p the cup resting against the hub flange, a cap'als'o fitted over the hub and having a peri heral edge resting against the disk cup, an bolts extending through the hub, disk and cap to temporarily secure them so as to be readily assembled and taken apart. 1

3. In a disk wheel, a disk having a cen tral straight hub-flange securing portion, a narrow annular shallow cupped portion between the central straight ortion and the peripheral edge, and a dished slightly curved wide annular portion between the cupped portion and the peripheral edge.

4. A disk wheel comprising a standard type of hub having a tubular central portion and rear flange, a flat bottomed centrall abruptly cupped disk fitting over the tubu ar portion and resting against the flange, a cap closely fitting over the outer end of the tubular portion of the hub and for use on standard wooden wheel hubs having a central tubular portion and rear strai ht flange, saiddisk comprisin a central at portion adapted to fit over t e tubular portion of the hub and seat against the inner face offthe hub flange, said flat portion extending. forwardly so as to form a cupwith an abrupt wall for receiving the radial thrust from the peripheral edge of a clamping cap, a narrow annular free or exposed shock-absorbing cup portion, and a wide dished disk portion extending from the annular cup substantially to the peripheral edge.

7. In a disk wheel the combination of a standard ty e of hub for wooden spokes havin a tu ular central portion and rear straig t flange with radia ly disposed bolt holes, a disk having a central portion with an abrupt annular wall and fitting over the tubular portion of the hub and seating on the inner face of the flange, a dished disk portion connecting the central portion and a rimsecuring periphery, a clamping cap closely fitting over the tubular portionof the hub and seating'against said abrupt annular wall so as to eflect a radial thrust thereon to support the disk, said cap havin bolt holes corresponding to the flange ho es, and bolts passingthrough the flange, disk and cap to clampsaid parts to ether- In witness whereof, I hereunto su scribe my name this 22nd day of October, A. D.,

GEORGE A. .MOCK.
